Hi, I'm Adebanjo Israel 👋

Cloud & Backend Engineer | AWS | Terraform | TypeScript | NestJS

I design and build secure, scalable cloud infrastructure and backend systems.

My work sits at the intersection of cloud engineering, platform automation and backend development. I use AWS, Infrastructure as Code and modern backend technologies to build systems that are reliable, maintainable and ready for production.

I am especially interested in:

  • AWS cloud infrastructure and architecture
  • Infrastructure as Code with Terraform and AWS CDK
  • Cloud networking, IAM and security
  • CI/CD and deployment automation
  • Distributed and event-driven backend systems
  • Node.js, TypeScript and NestJS applications
  • Platform engineering and developer self-service
  • System reliability, observability and performance

About Me

  • ☁️ Cloud Engineer with a strong backend engineering background
  • 🏅 AWS Certified Solutions Architect Professional
  • 🏗️ Building cloud infrastructure with AWS CDK and Terraform
  • ⚙️ Developing scalable backend services with Node.js, NestJS and TypeScript
  • 🚀 Automating delivery with GitHub Actions and AWS CI/CD services
  • 🔐 Interested in cloud security, IAM, least privilege and secure platform design
  • 🌍 Based in Lagos, Nigeria
  • 💼 Open to Cloud Engineer, Platform Engineer, DevOps Engineer and Backend Engineer opportunities

Highlights

  • Event-driven microservice architecture
  • Real-time bidding with WebSockets
  • Virtual wallet and transaction workflows
  • Kafka-based service communication
  • Redis caching
  • PostgreSQL persistence
  • AWS infrastructure provisioned with CDK
  • ECS Fargate, RDS, ElastiCache, MSK and S3 architecture

🧱 NestJS Multi-Database Microservice Starter

View Repository

A reusable NestJS monorepo starter for building backend applications with multiple databases, asynchronous workers and shared platform components.

Key technologies

NestJS 11 · PostgreSQL · MongoDB · RabbitMQ · Redis · Docker

Highlights

  • API gateway and service architecture
  • PostgreSQL and MongoDB support
  • RabbitMQ background workers
  • Shared authentication, validation and database modules

  • Docker-based local development
  • Installable through an npm scaffolding command

🧰 Backsnip

View Repository

An open-source collection of reusable solutions for common backend engineering tasks.

Backsnip helps developers find implementation examples across different programming languages and frameworks instead of repeatedly solving the same problems from scratch.

Highlights

  • Community-driven open-source project
  • Reusable backend implementation examples
  • Support for multiple programming languages
  • Contribution guidelines and public roadmap
  • Used to promote backend knowledge sharing and collaboration

🤖 Datie AI

View Repository

An AI-powered matching engine that combines semantic similarity with rule-based compatibility filtering.

Key technologies

TypeScript · Node.js · Gemini Embeddings · Pinecone · REST API

Highlights

  • Semantic profile embeddings
  • Vector similarity search
  • Rule-based compatibility filtering
  • Combined similarity and preference scoring
  • REST endpoints for profile processing and matching

What I Bring to a Team

I combine application development knowledge with cloud infrastructure experience.

This allows me to contribute across the full lifecycle of a system:

  1. Designing the backend architecture
  2. Building secure APIs and services
  3. Provisioning the required cloud infrastructure
  4. Automating testing and deployment
  5. Monitoring production workloads
  6. Troubleshooting application and infrastructure issues
  7. Improving reliability, security and developer experience

I care about building systems that do more than work locally. They should be secure, observable, repeatable and maintainable in production.


Currently Exploring

  • AWS multi-account platform architecture
  • Terraform module design and governance
  • Kubernetes and Amazon EKS
  • Platform engineering and developer self-service
  • AI-assisted cloud operations
  • Distributed systems and event-driven architecture
  • Cloud security and policy automation
